242 BIRDS OF INDIA. 



Ziigoclactyle Toucans of S. America, and are much more nearly 

 related to the Hoopoes, and In-isor, of the Tenuirostral tribe. They 

 are, indeed, popularly called Toucans throuohout India ; and this 

 appears to be their name in some of the Malayan isles ; the word 

 sio-nifying a worker, from the noise tliey make. 



The s-enus Buceros has of late been sub-divided into several 

 o-enera, most of which differ in the form of the bill, and the style 

 of coloration. Although, to some, it may at first sight appear an 

 unnecessary refinement to sub-divide birds of such a marked group, 

 yet, if it be considered that the Kingfishers (and many other famihes 

 as well) are just as marked a group as the Hornbills, and are sub- 

 divided into many genera, on what is considered ample grounds, it 

 will at once be conceded that there is equally sufficient reason for 

 dividing the Hornbills.
